Abstract

A tooth brush having, in addition to bristles, a plurality of magnetic projections on a handle of the tooth brush is provided for a massaging gums thereby preventing and remedying dental disease such as alveolysis, peris dentosis and the like. The magnetic projections are constituted of rod shaped synthetic resin members each incorporating therein a piece of permanent magnet, with each of the rod shaped members passing through the handle from the side not having bristles and being secured to a common base plate on the side of the handle not having bristles.

Description

  • This invention relates generally to a tooth brush and particularly, to a tooth brush having a plurality of projections provided in addition to the bristles of the tooth brush for massaging gums in addition to cleaning teeth.
  • Japanese Utility Model Publication 62-30983 shows a tooth brush having a plurality of projections provided in addition to the bristles of the tooth brush for massaging gums. It is described that the projections include, respectively, magnets which are particularly effective in preventing and remedying dental disease such as alveolysis, peris dentosis and the like.
  • The prior art projections having magnets have been mounted on the handle of the tooth brush from the side having bristles. The mounting operation is relatively easy, but such mounting is not reliable and durability thereof is poor.
  • According to the present invention, there is provided a tooth brush having bristles and a plurality of magnetic projections on a handle of the tooth brush, in which the magnetic projections are constituted of rod shaped synthetic resin members each incorporating therein a piece of permanent magnet, with each of the rod shaped members passing through the handle from the side not having bristles and being secured to a common base plate on the side of the handle not having bristles.
  • Each magnetic projection passes through each hole formed in the handle and, after passing through the handle the magnetic projections are secured to the common base plate respectively.
  • Further objects and advantages of the invention will become apparent from the following detailed description of preferred embodiment with reference to the drawings.
    • Fig. 1 is a schematic longitudinal sectional view of parts constituting a tooth brush according to a preferred embodiment of the present invention, and
    • Fig.2 is a schematic longitudinal sectional view of a tooth brush according to the present invention.
    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • In the drawing, shown at numeral 1 is a tip end portion of a handle of a tooth brush and, on which one ends of bristles 2 such as fur or nylon fibers and forming a plural lines and rows are secured to the handle by publicly known method.
  • There are provided at least one row of spaced apart through holes 5 in the handle 1. When one row of the holes 5 is provided, the row extends along the lengthwise extending center line (left and right directions in the drawing) of the handle. It is possible to provide two or more rows of the holes 5.
  • Shown at 4 is a member formed of a synthetic resin material and having a plural number of projections each having provided therein a rod shaped permanent magnet 3. The member 4 is mounted on the handle 1 with each of the projections passing through the holes 5. Thereafter, a base plate 7 is secured to the member 4 and to the handle 1 on the side of the handle 1 not having bristles 2. The portions of the member 4 projecting from the handle 1 constitute the magnetic projections according to the invention.
  • In the embodiment, the projections of the member 4 are connected together through a base portion 6, which simplifies production and mounting operations, however, it is possible to form rod shaped projections with permanent magnet pieces 3 incorporated therein and, after inserting respective projections through the holes 5 the base end portions of the projections 4 are connected to the base plate 7.
  • According to the invention, the magnetic projections are easily and reliably mounted on the tooth brush.
  • It will be understood that the invention is not limited to the embodiment, and various changes and modifications can easily be made for those skilled in the art within the scope of the present invention as defined by the claims.

Claims (2)
